"Steadily hang" the Pearl River 100 meters in the air! Zoomlion Tower Crane Helps Close Main Tower of Guangfo Bridge
March 01, 2023
Recently，With the help of Zoomlion Heavy Industry Tower Crane，Guang（State）Buddha（Mountain）Bridge System Phase I Project 100.Successful closure of the 5-meter-high main tower，The civil construction of this highly concerned livelihood project has achieved a major node.。Zoomlion Super Large Flat Head Tower CraneR4300-200 responsible for hoisting of main structural parts，Demonstrate excellence、Smooth、Precise lifting capacity。

Guangfo Bridge Phase I Project connects Nanhai, Foshan and Datansha Island, Guangzhou，The bridge is 278 meters long.。Considering the safety and stability of the western channel of the Pearl River，Combined with the navigation demand and geographical reality of the ship，As a super-large bridge, Guangfo Bridge is designed as an asymmetric structure with a single tower.，One side is 158 meters.，One side is 120 meters，And the steel main tower、Stay cable with central cable plan、Open steel box composite beam, etc.，And various process are involved，The overall construction is very difficult.。
To improve the speed of construction、Minimize construction impact，The project party adopts assembly construction.，First, a large number of prefabricated components are manufactured.，Then pull it to the design position of the site for assembly.，With“Build blocks”The way to build a bridge.。Because the construction process involves water operations.、Major schemes such as hoisting of large parts，But also has high requirement on manufacture and installation precision.、Large amount of heavy lifting operation、Multiple coordination work interfaces and the like.，To ensure the smooth lifting and installation of prefabricated structures，Project side、Leasing Company Joins Hands with Zoomlion，Tailor-made super-large tower craneR4300-200。

According to introduction，The main steel tower of Guangfo Bridge, more than 90 meters above the water surface, needs to be hoisted in sections.，The largest segment weighs 162 tons.，ByR4300-200 Tower Cranes Participate in Solving Hoisting Problems。“The highest independent height of this tower crane is 102 meters.，Surpass the current 99%The tower crane in use，Automatic climbing without any attached wall，Directly extend to 102m，And that rigidity of the tow body is large.、No deformation，It can resist 12 typhoons.，Combat the impact of other adverse factors，One step in place，Stable and excellent performance in construction。”The person in charge of the project praised the strength of Zoomlion's tower crane.。
R4300-Maximum rated lifting capacity of 200 tons for 200 tower crane，The lifting weight is in the forefront of the tower cranes currently in use.，The length of the main boom is 80 meters.。“R4300-The 200 has high performance、High security、High reliability、High efficiency‘Four high’Highlights，Work smoothly、Precise hoisting，At the same time, it is easy to assemble and disassemble、And is easy to maintain、Good transport，Very suitable for complex working conditions。It also has a variety of intelligence.、Visual operation，Remote control can be realized，No need to climb to the operating room.，High-altitude hoisting can be realized on the ground，It can safely and effectively solve the installation problem of super-high main tower.。”Zhao Weijuan, deputy manager of the flat arm tower crane platform of Zhonglian Heavy Branch Research Institute, said.。
